Match retail packaging weights to the pack version and parcel actually dispatched
Updated: Oct 19
A current pack specification cannot describe every gift set sold during a packaging change. An online order count also leaves split shipments unresolved. Build the quantity from the pack revision that accompanied each product and the extra packaging used for each physical parcel.
For retail procurement and fulfilment teams, the output is a component-by-component schedule for a named period and dispatch population. Count product packaging once across store and online routes, then add the packaging used to send online parcels.
Fix the population before multiplying
This fictional quarter covers one retailer and one gift-set line: 10,000 gift sets sold, comprising 6,000 old-pack and 4,000 new-pack units. Actual stock and batch records establish the revision split. A specification launch date alone would leave that split unconfirmed.
The same 10,000 sets comprise 6,500 store-sale units and 3,500 online units. The online units travel in 3,000 outbound parcels from 2,800 completed orders because some orders split. Every parcel uses one additional shipping box and one specified tape allowance.
All weights below are fictional, supported and fixed for the stated component and revision within the example. Cartons and shipping boxes are assumed cardboard; trays and tape are assumed plastic. These are material labels for this calculation.
Assume single-use packaging, no customer returns, dispatch reversals, cancellations, reuse or repacking, and no other relevant components. Store carry bags are absent. The schedule measures only the listed packaging accompanying completed store sales and outbound customer parcels.
Calculate the six component quantities
For each component, multiply its matched count by grams per item and divide by 1,000 to obtain kilograms.
Old product carton
6,000 old-pack units × 80 g ÷ 1,000 = 480 kg of cardboard.
New product carton
4,000 new-pack units × 70 g ÷ 1,000 = 280 kg of cardboard.
Old product tray
6,000 old-pack units × 20 g ÷ 1,000 = 120 kg of plastic.
New product tray
4,000 new-pack units × 12 g ÷ 1,000 = 48 kg of plastic.
Additional parcel box
3,000 parcels × 120 g ÷ 1,000 = 360 kg of cardboard.
Additional parcel tape
3,000 parcels × 5 g ÷ 1,000 = 15 kg of plastic.
Product packaging is 480 + 280 + 120 + 48 = 928 kg. Additional parcel packaging is 360 + 15 = 375 kg. Together they give 1,303 kg for the listed dispatch population.
The material check gives 1,120 kg cardboard and 183 kg plastic, also totalling 1,303 kg. Product cartons and trays for the 3,500 online units are already inside the 928 kg; adding them again would duplicate them.
Check the three tempting shortcuts
Online units as box count: 3,500 × 120 g ÷ 1,000 = 420 kg, overstating boxes by 60 kg.
Orders as box count: 2,800 × 120 g ÷ 1,000 = 336 kg, understating boxes by 24 kg.
Newest tray weight for every unit: 10,000 × 12 g ÷ 1,000 = 120 kg, understating trays by 48 kg against the correct 168 kg.
These box errors leave tape unchanged for comparison. The data establishes the combined product-packaging total, but supplies no old/new split within each sales route. A separate store-versus-online product-packaging subtotal needs that additional mapping.
Ask for the records that determine each multiplier
Request the component weight and material for each revision, the stock or batch records linking those revisions to actual sold or dispatched units, and the parcel-packing records linking additional boxes and tape to physical shipments. Retain original units and source references beside each calculation. If a join is missing, leave the affected quantity unresolved rather than substituting the newest weight or assuming one parcel per order.
GS1 Finland's Synkka packaging guidance links packaging components to materials and records material weights in grams. The dispatch calculation here is an original working example.
The 500 unused empty shipping boxes held at period end stay outside this dispatch schedule. Keep unused stock and on-site packaging waste in separate schedules. Their quantities cannot be added to dispatched packaging merely because they concern the same material.
For a real population, add any missing components and define how returns, reusable packaging or repacking affect the event being measured before extending the calculation. No general subtract-returns rule follows from this closed case.
